The above table provides information about New South Wales, Victoria and South Australia. Sustainable diversion limit (SDL) areas not shown in the table may have values relevant to the line item, however, relevant information was not available for the 2012 Account. No information was available to be reported from Queensland or Australian Capital Territory as there are currently no approved groundwater sharing plans for these jurisdictions.

Quantification approach

Data source

New South Wales water sharing plans, Victorian Water Accounts 2010–11, Upper Ovens River Water Management Plan 2012 and South Australia water allocation plans.


Provided by

Bureau of Meteorology (the Bureau).

Method

Extractions were extracted from the relevant clauses in the jurisdictional groundwater plans.

Assumptions, limitations, caveats and approximations

The Bureau assumed that the volume of groundwater extracted under other statutory rights is the same as the water requirements estimated for these rights at the commencements of the water management plans.

The volume reported for groundwater extracted under other statutory rights is likely to be underestimated as limited data was available.

Uncertainty information

The uncertainty estimate was not quantified.

Comparative year

The following changes resulted in the restatement of the 2010–11 year volume:

  • scope change
  • error correction.

The changes and their respective values are detailed in the following table.


 

Restatement of comparative year information made for the line item 18.7 Groundwater extractions – Other statutory groundwater rights
2011 Account line item Segment Volume at 30 June 2011 reported in the 2012 Account (ML) Volume at 30 June 2011 reported in the 2011 Account (ML) Difference due to scope change and prior period correction (ML)
18.7 Extraction: other statutory rights  Northern Basin 12,858 12,858 0
Southern Basin 36,437 10,825 25,612
Whole region 49,295 23,683 25,612


Scope change was due to the following reason:

  • Information on other statutory right extractions for several groundwater management areas and water supply protection areas in Victoria was not included in the 2011 Account. The areas are Alexandra, Barnawatha, Kinglake, Loddon Highlands, Lower Ovens, Mid-Goulburn, Mullindolingong, Upper Ovens, Little Desert, Nhill and unincorporated areas. Information for these areas has been included in the 2012 Account. Resulting volume for this scope change is 18,368 ML.

Prior period error correction was due to the following reasons:

  • Information on other statutory right extractions for several Victorian groundwater management areas and water supply protection areas for which entitlement volumes were provided was not included in the 2011 Account. The areas are Katunga, Lower Campaspe valley, Mid-Loddon, Shepparton Irrigation Region, Balrootan, Goroke, Kaniva, Murrayville and Telopea. Information for these areas has been included in the 2012 Account. Resulting volume for this scope change is 6,974 ML.
  • Information on other statutory right extractions for Marne Saunders SDL area in South Australia (270 ML) was not included in the 2011 Account.
